Billet Upper Receiver Design

The Vertex Enhanced Pistol Caliber upper is machined from 6061-T6 billet aluminum and finished with Type III hard coat anodizing. This construction provides structural rigidity and corrosion resistance while maintaining the tight tolerances required for reliable 9mm operation. The billet design also allows for integrated features and cleaner lines compared to forged alternatives.

MVR Reflex Sight Integration

The included MVR reflex sight offers dual-color reticle capability, switching between red and green depending on lighting conditions and shooter preference. The sight mounts directly to the upper receiver, eliminating the need for additional optic purchases and keeping your total setup cost lower. This is a complete ready-to-shoot package once you add the lower receiver.

9mm Specific Bolt Carrier Group

The included 9mm bolt carrier group uses 8620 alloy steel with nitride finish, designed specifically for 9x19 Parabellum ammunition. The 1:10 barrel twist rate pairs with standard 9mm projectiles for reliable cycling and accuracy. The complete buffer system uses carbine-length components tuned for 9mm operation, ensuring consistent lock timing and ejection.

Lower receiver not included. BCG and charging handle are included with this kit. Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws.
